Description

Dimming panel

The invention relates to a dimming panel. In particular, the present invention relates to a dimming panel comprising a heatable transparent conductive layer and a light transmissive layer with adjustable transmittance.

The panel structure, for example, is applied to a glass window in a car, and may be made of heat-insulating paper or a material such as dyed glass for shading, glare, or privacy. However, such a panel structure having a occlusion or isolation function may simultaneously obstruct the line of sight, so that a person on one side of the panel structure inspects the line of sight on the other side is limited. For example, the driver's view through the glass window to the outside of the car is limited, thereby increasing the risk of driving the car. In addition, when the owner is outside the car, it is difficult to clearly understand the situation inside the car. Therefore, there is a need to develop a panel structure that can change transmittance or transparency depending on conditions or needs.

Further, when the panel structure is arranged to separate different environments, moisture may be condensed to adhere to the panel structure due to the temperature difference between the two sides. Alternatively, fog or frost in one side of the environment may undesirably adhere to the panel structure. In view of this, there has been a technique of installing a heating wire to remove the mist and dew. However, heating the wire unnecessarily reduces the aesthetics of the panel structure and may hinder visibility through inspection of the panel structure. In addition, if the layout pitch is too large, the heating of the metal wire may cause the panel structure to be broken due to the difference in thermal expansion.

In order to solve the above problems, an embodiment of the present invention provides a dimming panel including a first substrate, a dimming layer disposed on the first substrate and changing transmittance based on a power supply, and a dimming layer disposed opposite to the first a second substrate on one side of the substrate, at least one electrode layer disposed between the light control layer and the first substrate or between the light control layer and the second substrate, and disposed on the second substrate and having the first end And a transparent conductive layer at the second end. The transparent conductive layer conducts current from the first end to the second end based on the power supply.

According to the dimming panel provided by the present invention, the transmittance can be adjusted and changed based on the condition or demand to achieve the desired visibility and/or obscuration. Further, the dimming panel provided by the present invention can also remove the mist dew that may hinder the line of sight and reduce the influence on the integrity and aesthetics of the dimming panel.

Referring to FIG. 1 , according to an embodiment of the present invention, the dimming panel 1000 may include a first substrate 100 , a dimming unit 400 disposed on the first substrate 100 , a second substrate 200 disposed on the dimming unit 400 , and The transparent conductive layer 600 is disposed on the second substrate 200 and has a first end 601 and a second end 602. Specifically, the dimming unit 400 can include at least one dimming layer 450 disposed on the first substrate 100, and the second substrate 200 can be oppositely disposed on the dimming layer 450 opposite to the first substrate 100. One side. Wherein, the dimming layer 450 can change the transmittance based on the power supply, and can be, for example, an electrochromic layer, or can be a liquid crystal layer. However, the above are all examples and the present invention is not limited thereto.

In order to supply power to the light-adjusting layer 450, at least one electrode layer may be disposed at least between the light-adjusting layer 450 and the first substrate 100 or between the light-adjusting layer 450 and the second substrate 200. For example, according to an embodiment of the present invention, as shown in FIG. 1 , the dimming layer 450 may be a liquid crystal layer, and the first electrode 410 as a driving electrode may be disposed between the dimming layer 450 and the first substrate 100, and The second electrode 420 as a common electrode may be disposed between the light control layer 450 and the second substrate 200. Thereby, the electric field of the dimming layer 450 can be changed by supplying power to the first electrode 410 and the second electrode 420 to change the alignment of the liquid crystal molecules to adjust or change the transmittance of the dimming layer 450. However, the above is merely an example, and the present invention is not limited thereto. For example, when the dimming unit 400 is a liquid crystal display unit using IPS or FFS technology, only one of the first electrode 410 or the second electrode 420 may be disposed.

According to still another embodiment of the present invention, when the dimming layer 450 is a liquid crystal layer, the dimming layer 450 can be driven by an active matrix configuration or a passive matrix configuration. Wherein, if the dimming layer 450 is driven by the passive matrix configuration, the aperture ratio of the dimming layer 450 can be further improved because no metal lines such as data lines and/or gate lines are provided. Therefore, the transmittance of the dimming layer 450 can be further improved, thereby improving the transmittance of the entire dimming panel 1000. However, in the case where the resolution is sufficiently high, the dimming layer 450 can also be driven by the active matrix configuration and still achieve the desired transmittance of the dimming panel 1000.

Thereby, the transparent conductive layer 600 can raise the temperature due to the load of the current, thereby evaporating the misty dew which may adhere to the dimming panel 1000 as a heating sheet. As described above, based on the high transmittance of the transparent conductive layer 600, the transparent conductive layer 600 is more difficult to be recognized by the naked eye, so that the integrity of the dimming panel 1000 can be maintained while acting to remove the mist dew. And aesthetics.

According to an embodiment of the present invention, the goal of disposing the transparent conductive layer 600 can be achieved by providing a separate panel structure including the transparent conductive layer 600 on the independent panel structure including the light adjustment layer 450.

In this case, the transparent conductive layer 600 may be a layer formed on the second substrate 200 in an evaporated, coated, or deposited form. In addition, a third substrate (eg, a protective substrate) may be further disposed on one side of the transparent conductive layer 600 opposite to the second substrate 200 to protect the transparent conductive layer 600, regardless of the form in which the transparent conductive layer 600 is disposed.

As shown in the above, the dimming panel 1000 can adjust the transmittance of the dimming layer 450 by using a power supply, and the transparent transparent conductive layer 600 can be turned on by the power supply, and the power supply of the two can be separately or simultaneously . Therefore, the transmittance (or gray scale) of the dimming panel 1000 can be adjusted based on the situation or demand, and the mist dew attached to the dimming panel 1000 can be removed.

According to some embodiments of the present invention, at least one base layer may be further disposed on at least one of the two outermost surfaces of the dimming panel 1000 to further enhance the dimming panel. The overall thickness of 1000, or improve the structural strength of the dimming panel 1000.

According to a preferred embodiment, the structural strength (eg, tensile strength, compressive strength, flexural strength, etc.) of the base layer may be higher than the first substrate 100 or the second substrate 200. Further, the base layer may be tempered glass, but the present invention is not limited thereto.

For the sake of brevity, the electrodes that are supplied to the light-adjusting layer 450 and the bonding pads 700 that are supplied to the transparent conductive layer 600 may be omitted in the dimming panels 1010 to 1060. In addition, here, the polarizing layer 41 relatively close to the transparent conductive layer 600 may be defined as the first polarizing layer 41, and the polarizing layer 42 relatively far from the transparent conductive layer 600 may be defined as the second polarizing layer 42.

As shown in FIG. 2A to FIG. 2F , in a case where the light adjustment layer 450 is a liquid crystal layer, the light adjustment layer 450 is disposed between the first polarizing layer 41 and the second polarizing layer 42 . Therefore, the dimming layer 450 can better adjust the transmittance and light transmission characteristics of the entire dimming panels 1010 to 1060 by combining the first polarizing layer 41 and the second polarizing layer 42.

According to an embodiment of the present invention, in addition to the polarizing layer that can be assembled by attaching, the first polarizing layer 41, the second polarizing layer 42 or a combination thereof is indicated by an asterisk in FIGS. 2A to 2F.

Wherein, according to the embodiment, the light adjustment layer 450 may be a liquid crystal layer. In this case, the dimming panel 1100 can further include an AC power source 810 electrically coupled to the dimming layer 450 and driving the dimming layer 450 to change the transmittance. In addition, the dimming panel 1100 can further include a DC power source 820 electrically coupled to the transparent conductive layer 600 and driving an on current to the transparent conductive layer 600 to increase the temperature of the transparent conductive layer 600.

Next, an arrangement form of the bonding pad 700 electrically connecting the transparent conductive layer 600 and the power source 800 according to various embodiments of the present invention will be described with reference to FIGS. 4A to 4C. 4A to 4C are plan views taken along the line A-A of Fig. 1. However, the combined configuration of the transparent conductive layer 600 and the bonding pad 700 shown in FIGS. 4A to 4C is not limited to the embodiment applied to the dimming panel 1000 shown in FIG. 1, and can be applied to other implementations of the present invention.

Here, the length of the first bonding pad 710 and the second bonding pad 720 may be equal to or greater than the length of the side of the side end of the complete sheet-shaped transparent conductive layer 605. In this configuration, the first bond pad 710 and the second bond pad 720 can be connected to the power source 800, for example, by wires 910 and wires 920, respectively, to achieve conductive heating of the complete sheet-like transparent conductive layer 605. According to the embodiment, the process and the arrangement for preparing the dimming panel can be relatively simple.

In addition, as shown in FIG. 4B, according to another variant embodiment of the present invention, the transparent conductive layer 600 may be a plurality of block-shaped transparent conductive layers that are divided. For example, six block-shaped transparent conductive layers 610, 620, 630, 640, 650, and 660 are shown in FIG. 4B. However, the number of the block-shaped transparent conductive layers of the present invention is not limited thereto, and this is merely an example. In this case (the transparent conductive layer 600 is divided), the bonding pad 700 may include a first bonding pad 710 and a second bonding pad 720. The first bonding pad 710 and the second bonding pad 720 can be respectively connected to one side ends of the respective block-shaped transparent conductive layers 610 to 660.

That is, one of the bonding pads 710 is connected to one side of the block-shaped transparent conductive layers 610 to 660, and the other bonding pad 720 is connected to the other side of the block-shaped transparent conductive layers 610 to 660. In this configuration, the first bonding pads 710 and the second bonding pads 720 can be connected to the power source 800, for example, by wires 910 and wires 920, respectively, thereby achieving conductive heating of the block-shaped transparent conductive layers 610 to 660. According to the embodiment, the damage or deterioration of the local block-shaped transparent conductive layer can be prevented from affecting the overall transparent conductive layer.

Further, as shown in FIG. 4C, according to still another modified embodiment of the present invention, the transparent conductive layer 600 can be divided into a plurality of block-shaped transparent conductive layers similar to the embodiment of FIG. 4B, and similar or identical details will be No longer. However, in this case (the transparent conductive layer 600 is divided), the bonding pad 700 may include a plurality of first bonding pads 701 to 706 and a plurality of second bonding pads 701' to 706'. The bonding pads 701 to 706 and 701' to 706' may be respectively connected to one side end of at least one of the block-shaped transparent conductive layers 610 to 660 or opposite to the other side end of the side end. Specifically, the block-shaped transparent conductive layers 610 to 660 each have a first side opposite to the first end 601 and a second side of the second end 602, and the first bonding pads 701 to Each of the 706 and each of the second bonding pads 701 ′ 706 ′′ extend along at least one of the first side edges and at least one of the second side edges. In this configuration, the bond pads attached to the two side ends of one of the block-shaped transparent conductive layers can be connected to the power source, for example, by different wires, respectively, thereby achieving conductive heating of the block-shaped transparent conductive layer. For example, the bonding pads 701 and 701' connected to both side ends of the block-shaped transparent conductive layer 610 can be connected to a power source by different wires, respectively. In addition, the power sources to which the different block-shaped transparent conductive layers are connected may be the same or different. According to the embodiment, it is possible to prevent the damage or deterioration of the local block-shaped transparent conductive layer from affecting the operation of the entire transparent conductive layer 600, and each of the block-shaped transparent conductive layers 610 to 660 can be externally, for example, by external The signal is independently controlled and turned on, thereby enabling local heating, zone heating or detailed temperature adjustment of the dimming panel.

According to an embodiment of the present invention, referring to FIG. 4B and FIG. 4C, in order to make the transparent conductive layer 600 conductive, the overall dimming panel has better heating uniformity and/or improve the appearance and appearance of the dimming panel. The spacing d between the adjacent block-shaped transparent conductive layers 610 to 660 is preferably less than 50 μm. However, the present invention is not limited thereto, and the spacing d may be based on the material of the transparent conductive layer 600. The material characteristics and cost vary with the desired heating characteristics or appearance characteristics of the dimming panel.

Next, the application and manipulation of the dimming panel according to various embodiments of the present invention will be described with reference to FIG.

Referring to FIG. 5, according to an embodiment of the present invention, the dimming panel of any of the above embodiments can be applied as the windshield 2100 behind the automobile 2000. Therefore, the transmittance of the rear windshield window 2100 can be adjusted by using the dimming panel (including the dimming layer 450) of the above embodiment, so that the light incident from the rear windshield window 2100 can be adjusted. For example, the ambient light 510 entering from the rear windshield window 2100 can be incident into the vehicle with the adjusted intensity or characteristic light 520 after passing through the rear windshield window 2100, and may be viewed directly by the person inside the vehicle. Entering the eyes of the person inside the vehicle, or further reflecting the light 530 by the rear view mirror 2200 into the eyes of the person inside the vehicle.

For example, according to this embodiment, when driving the automobile 2000 at night or poor visibility, the rear windshield window 2100 may be included in order to make the image behind the automobile 2000 clearly visible (may include any embodiment) The light transmittance of the dimming panel is increased. For example, the electric field can be manipulated such that the alignment of the liquid crystal molecules of the dimming layer 450 of the liquid crystal layer is changed to increase the transmittance. Therefore, the insider can see the relatively clear and high-brightness rear image by reflecting the rear view mirror 2200 or directly looking rearward.

On the other hand, if the person in the vehicle is not glare or affected during daylight or strong light (for example, rear light), the rear windshield window 2100 may be included (may include any embodiment) The transmittance of the dimming panel is reduced. For example, the electric field can be manipulated such that the alignment of the liquid crystal molecules of the dimming layer 450 of the liquid crystal layer is changed to reduce the transmittance. Therefore, the insider can avoid direct sunlight or sun exposure to the sun by the rear view mirror 2200 or directly to the rear.

In order to adjust the transmittance of the dimming panel with respect to factors such as ambient light, According to some embodiments of the present invention, the transmittance may be adjusted based on a manual operation of the user (eg, a remote control). In addition, according to other embodiments of the present invention, the dimming panel can further communicate with a light sensor 3000 to adjust the transmittance of the dimming layer 450 based on the light intensity detected by the light sensor 3000. The light sensor 3000 can be disposed on the dimming panel (embedded in the outermost side of the dimming panel) or independently of the dimming panel.

Under the light sensor 3000, according to an embodiment, a predetermined transmittance can be set. Therefore, if the light sensor 3000 senses that there is strong light behind or the ambient light intensity is high, it can communicate with the dimming panel to reduce the transmittance of the dimming panel. Conversely, if the light sensor 3000 senses low brightness or the rear visibility is lowered, it can communicate with the dimming panel to increase the transmittance of the dimming panel.

According to still other embodiments of the present invention, the transmittance of the dimming panel can also be adjusted according to personal privacy requirements, needs for sun exposure, and the like. For example, it is possible to switch to the lowest transmittance in the non-driving state to avoid being peeped by unrelated persons. However, when the relevant person needs to inspect the inside of the vehicle without entering the vehicle, the corresponding operation can be performed to switch the transmittance of the dimming panel to a higher state for a short period of time.

In addition, according to the embodiment, since the rear windshield window 2100 (which may include the dimming panel of any of the embodiments) is provided with the transparent conductive layer 600, it can be evaporated by heating the transparent conductive layer 600 when the mist dew occurs. Fog frost dew. Therefore, the visibility of the automobile 2000 and the safety of driving can be improved.

According to some variant embodiments, when the dimming panel is applied to a cold area or country, since the dew is easily formed on the dimming panel on the side of the warm room (for example, inside the car 2000), the dimming panel can be mounted to make the transparent conductive Layer 600 faces the room relative to dimming layer 450. Therefore, Accelerate the process of heating the mist and dew on the dimming panel on the inside of the evaporation chamber. However, this is merely an example, and the orientation of the dimming panel of the present invention is not limited to this based on environmental changes, characteristics, and requirements.

The above description of the application of the dimming panel according to the embodiments of the present invention to the rear windshield of the automobile is merely an example, and the dimming panel according to various embodiments of the present invention can be applied to various installations to separate the two sides of the space. Or on the window of the environment, or can be applied to any panel structure that adjusts the transmittance or removes the mist and dew, and can be adjusted and changed according to the above principles. In addition, according to some embodiments of the present invention, when the light adjustment layer 450 is a liquid crystal layer, the liquid crystal molecules can increase the reaction speed based on the relatively high temperature at which the transparent conductive layer 600 conducts heating. Therefore, it is possible to further avoid the defect that the reaction time of the liquid crystal molecules may be elongated when the environment is relatively low.

As described above, according to the dimming panel of each embodiment of the present invention, the transmittance can be adjusted depending on the situation and the expectation, and the attached mist and dew can be removed. Further, the above different functions of adjusting the transmittance and removing the mist dew can be operated independently, and can be performed simultaneously or at different times. Therefore, the applicability and flexibility of the dimming panel can be further improved.

The foregoing description is only some of the preferred embodiments of the present invention. It should be noted that various changes and modifications can be made in the present invention without departing from the spirit and scope of the invention. It should be apparent to those skilled in the art that the present invention is defined by the scope of the appended claims, and that various changes, combinations, modifications, and alterations may be made without departing from the scope of the present invention. The scope defined by the scope of the appended patent application.
